Senior Customer Success Manager

Cortex helps engineering teams ship better software faster. We're an AI-powered Internal Developer Portal that enforces reliability standards across every team automatically, so organizations can move fast without breaking things. Our customers reduce incidents by 30%, cut MTTR by an average of 50%, and ensure that AI code doesn't compromise service quality.

We’re looking for a Senior Customer Success Manager to join our growing Customer Success team. As a Sr. CSM at Cortex, you’ll be the strategic partner for some of our largest and most sophisticated customers — ensuring they realize tangible business outcomes while also navigating the technical depth of our platform and the broader engineering ecosystem. You’ll build deep relationships across all levels of a customer’s organization, from hands-on engineering leaders to C-suite executives. Success in this role requires an exceptional ability to bridge technical expertise with strategic business value, guiding customers both through tactical implementation details and big-picture conversations about productivity, efficiency, and ROI. You’ll be both a trusted technical advisor and an executive-level consultant. This is a high-impact, high-ownership role perfect for someone who thrives in fast-paced environments, brings a strong technical foundation, and is passionate about delivering outcomes that matter.
